How do you make metal into different shapes?
Metal is normally very hard, so it doesn't bend. But when you make metal very hot, it bends easily. Once you heat up the metal, you can hit it with a hammer so that it becomes the right shape.
This man is making a big bowl out of a metal called copper. He is putting it over the fire so that the metal will become very hot. He is using a special tool to hold the metal so it doesn't burn him.
Copper can be used to make a lot of different things. A long time ago people used to make weapons out of it. Today, some countries make their money out of it. Some computer parts are made with copper.
